What is Bitumen 85/100?
Bitumen 85/100 is a premium brand that is dark brown or black in color similar to cement-shape semi-solid or viscous liquid form produced by the non-destructive refining of crude oil during petroleum refining.
Bitumen Grade 85/100, a versatile and essential construction material, serves as the backbone of modern infrastructure. Among the array of bitumen grades, Bitumen 85/100 stands out for its distinct properties and wide-ranging applications.
Bitumen Penetration Grade 85/100 is classified based on its penetration and viscosity properties, with the numbers representing the penetration depth in tenths of a millimeter at a standard temperature of 25°C.
Uses of Bitumen 85/100
The main common usage of this product is in road making in cold regions. Penetration 85/100 is suitable for road construction and for asphalt pavements with superior properties. This type of asphalt is used in the manufacture of hot mix asphalt for bases and wearing courses and the main usage of this product is used in the spaying and chip application.
The asphalt is provided during the presses of oxidation of vacuum bottoms in asphalt production units. Due to its relatively low air blowing and penetration, It is used in areas with cold weather for asphalting and insulation. It is not cracked in low temperatures.
Application of Bitumen 85/100
Penetration 85/100 finds diverse applications within the construction industry, shaping infrastructure development and longevity:
- Road Construction: A cornerstone of road construction, Bitumen 85/100 serves as a binder in asphalt mixes. Its specific properties create stable road surfaces capable of enduring varying traffic volumes, weather conditions, and environmental stresses.
- Pavement Preservation: The application of Grade 85/100 in pavement preservation techniques, such as micro-surfacing and slurry seals, contributes to the enhancement of existing roads, reducing cracks and enhancing skid resistance.
- Waterproofing and Roofing: Its waterproofing capabilities make Penetration 85/100 a popular choice for waterproofing basements, roofs, and other structures, ensuring protection against moisture intrusion.
- Industrial Applications: Beyond construction, Grade 85/100 finds utility in various industries, including the production of coatings, adhesives, and sealants.
Properties of Bitumen 85/100
Bitumen Penetration 85/100 is classified based on penetration and viscosity, with the numbers representing the penetration depth in tenths of a millimeter at a standard temperature of 25°C. The “85” in 85/100 signifies that the bitumen has a penetration value between 85 and 100 at the specified temperature.
- Penetration Value: Falling within the 85 to 100 penetration range, Bitumen 85/100 strikes a balance between hardness and workability. This property makes it versatile and suitable for various applications, particularly those requiring a degree of flexibility.
- Viscosity: Bitumen 85/100 boasts moderate viscosity, enhancing its ease of mixing and application. Its ability to bind effectively with aggregates plays a pivotal role in constructing durable and robust road surfaces.
- Adhesion and Cohesion: The excellent adhesion of Bitumen 85/100 ensures optimal bonding between bitumen and aggregates, resulting in long-lasting roadways. Furthermore, its cohesive nature prevents cracking and disintegration, even under challenging conditions.
- Durability: Bitumen 85/100’s resilience to temperature fluctuations and traffic loads, owing to its elasticity, contributes to the durability and longevity of road surfaces, ultimately reducing maintenance requirements.
Bitumen 85/100 is Elastic and Plastic
When one takes a thread of bitumen 85/100 from a sample and stretches or elongates it, it is the power to return to a length preparing to its original length eventually.
For many Bitumens 85/100 this technique might take longer than others.
The properties are mentioned as a result of the elastic character of bitumen.
When the temperatures unit of measurement is raised, equally as once a load is applied to bitumen 85/100, the asphalt 85/100 will flow, but will not come back to its original position once the load is removed.
This condition is alleged as plastic behavior. Applying a load implies that you simply place a weight on the bitumen 85/100, therefore, subjecting it to fret.
This may well be throughout a groundwork science lab or at intervals the asphalt 85/100 final position at intervals the road and it’s done to assess the asphalt 85/100 reaction to the load.
